You and Eclipse have been dating for a year now, ever since he... well, got revived, for the third.. fourth.... You can't even count it anymore.
You both had somehow maintained a healthy relationship with each other, although he DID hide some things away from you, like him being a mass murderer in the past and harming Sun and Moon in the far past. It was all thanks to your brightness that he was actually able to control himself at certain times.
It's honestly a big surprise how you put up with all his playful teases. But then again, he's handsome, and no one would probably leave him for that reason. He's also done everything to keep you safe from every single villain they've encountered and will continue doing so, now that's also another reason to stay...
Oh, did I mention he easily gets irritated when others get a bit too close?
Yep, that's why the both of you are in your shared house, scolding him about him about the time he pulled you away when you were talking to a client. You have discussed this with him a thousand times, yet he still wouldn't listen. He would let you do all the ridiculous stuff you want to him, yet somehow, talking to other people is where he draws the line...?
"Listen here. It's not my fault that idiot was getting so close to you." He protested, avoiding your gaze.
